Do you know if is it possible to set specific privileges on individual OS users when accessing to fs mounted thorugh DBFS?. As I have seen, there are only these possibilities: root, oracle and others. But If I want to set read permissions for OS user A on DBFS filesystem and write permissions for OS user B on the same filesystem, is it possible?.
The directory/file permission settings on dbfs are similar as a normal Linux filesystem.
If you have user O (=owner) who owns the file and you have user A who is not in the group of O you have to make the file readable for the world.
For user B to be able to write to the file he than needs to be in the same group and the group permission for the file should be set to write.
